| Abstract: | The thermal stress field in the functional graded materials(FGMs) plane is investigated.First of all,the stress caused by the thermal has been obtained by introducing the displacement function.Secondly,the stress on no consideration of the thermal has been derived by using Airy stress function.At last,the general solution of the thermal stress is given on the bases of the stress adding. |
